Lennox International Inc. (LII) drops 8.5% on EPS miss
Lennox International Inc. (LII) drops after reporting Q3 adjusted EPS below estimates and cutting full-year guidance. Revenue rose, but weaker margins and softer residential demand overshadowed commercial strength, sending the stock near its 52-week low and resetting investor expectations.
Lennox International Inc. (LII) dropped 8.5% after Q3 adjusted EPS came in below estimates and management sharply lowered full-year 2026 earnings guidance. The selloff reflects a market reset around weaker margins and softer residential demand, even as revenue growth and commercial HVAC strength remain intact. For investors, the key issue is now earnings quality, not top-line growth.
Why Lennox International Inc. (LII) Drops 8.5% Today
Lennox International Inc. (LII) drops 8.50% to $340.42 at 11:05 ET on Oct. 28, 2026, putting the stock within cents of its $340.32 52-week low. The move follows Q3 adjusted diluted EPS of $6.84 versus a $7.18 estimate and a sharp cut to full-year earnings guidance.
Key Takeaways
LII drops 8.50% on Oct. 28, while relative volume reaches 1.6x its 200-day average.
The direct catalyst is Q3 adjusted EPS of $6.84, below the $7.18 estimate and down 7% year over year.
Lennox cut full-year 2026 adjusted EPS guidance to $21.00-$21.50 from $23.00-$24.00.
Revenue growth and commercial strength are positives, but weaker margins and residential demand now dominate the investment debate.
What's Behind Lennox International Inc. (LII)'s 8.5% Selloff
The catalyst arrived before the market opened. Lennox reported Q3 revenue of about $1.6B, up 10% year over year, but adjusted diluted EPS fell 7% to $6.84. That result came in below the $7.18 estimate listed in the recent earnings history.
The bigger shock was the outlook. Lennox reduced full-year 2026 adjusted EPS guidance to $21.00-$21.50 from $23.00-$24.00. It also set full-year revenue growth guidance at about 6%, including a 5% benefit from completed acquisitions. For the market, the earnings reset matters more than the strong headline revenue number.
Trading activity reinforces that interpretation. LII's relative volume reached 1.6x its 200-day average by 11:05 ET. The stock also entered the report under pressure, closing at $372.05 on Oct. 27 with 925,441 shares traded against a 30-day average of 499,670 shares. This is an earnings-driven repricing, not a quiet drift toward a yearly low.

Lennox Revenue Growth Is Not Converting Into Profit
Lennox's Q3 results show a split business. Building Climate Solutions revenue increased 24%, including 15% organic growth. Commercial HVAC, refrigeration, and services provided notable strength. That performance gives the company exposure to areas that are holding up better than residential heating and cooling.
However, segment profit fell 2%, and segment margin declined 240 basis points to 20.6%. That is the central problem behind the selloff. Lennox is growing sales, but less of each sales dollar is reaching profit. GAAP operating income was $312M, while the adjusted EPS decline showed the pressure at the shareholder level.
The residential market adds another layer of risk. Lennox's business depends on replacement demand, housing activity, weather, raw material costs, and service work. The company said residential end markets were only beginning to stabilize. Therefore, commercial growth is carrying more of the near-term story while residential demand remains a drag.
What LII's Valuation and HVAC Position Say After the Drop
At $340.42, Lennox has a market value of $11.76B and a displayed P/E ratio of 16.4. The 1.44% dividend yield offers some shareholder return, but the valuation cushion is less convincing after the company lowered its earnings outlook. A lower share price does not automatically create value when the earnings base is also moving lower.
Lennox still has a broad operating position across residential and commercial HVAC, refrigeration, indoor air quality, controls, parts, and services. Its peer group includes Carrier Global, Trane Technologies, Johnson Controls, AAON, and Watsco. The Q3 commercial result supports Lennox's competitive relevance, but the margin decline shows that scale and demand do not guarantee steady profit conversion.
Analyst actions had already turned cautious before the earnings report. Goldman Sachs downgraded Lennox to Neutral on Oct. 14, and Mizuho cut its price target to $395 from $450 on Oct. 15. The current analyst consensus is Hold, with 8 Buy ratings, 18 Hold ratings, and 4 Sell ratings. Those actions did not cause today's move, but they left less support around the stock before the guidance cut.
How Lennox Investors Can Frame the New Earnings Outlook
The cleanest framework is to treat LII as an earnings-reset story. The new $21.00-$21.50 adjusted EPS range is the proper near-term anchor, not the previous $23.00-$24.00 range. Investors assessing the stock at $340.42 can now judge the valuation against the lower profit outlook and the 20.6% segment margin.
Three facts deserve priority. First, commercial revenue growth of 24% gives Lennox a working source of demand. Second, 15% organic growth shows that acquisitions are not the entire commercial story. Third, the 240-basis-point margin decline explains why revenue strength failed to protect EPS. A recovery case needs those three facts to move in the same direction.
News sentiment also gives a useful warning. The seven-day sentiment score is 0.7718, still classified as strongly positive, but it has deteriorated from 0.8698 over 90 days. That gap shows how quickly a favorable narrative can weaken when guidance changes. In practical terms, a contrarian buyer can focus on the $340.32 52-week low, but a durable recovery thesis requires improving margins and firmer residential demand.
What Lennox International Inc. (LII)'s Drop Means for Investors
LII drops because Q3 profit missed the $7.18 estimate and Lennox reduced full-year adjusted EPS guidance to $21.00-$21.50. Revenue growth and commercial HVAC strength remain meaningful positives, but margin compression and weak residential conditions now define the stock's risk profile.
The actionable takeaway is simple: judge Lennox on earnings quality, not revenue growth alone. The stock can become attractive if commercial momentum persists, residential demand stabilizes, and the 20.6% segment margin begins to recover. Until then, the guidance cut deserves more weight than the lower share price.
LII is down because Lennox reported Q3 adjusted EPS of $6.84, below the $7.18 estimate, and cut full-year 2026 adjusted EPS guidance to $21.00-$21.50. Investors are also reacting to margin pressure and softer residential demand.
+Should I buy LII stock now?
The stock may interest long-term investors, but the guidance cut means the near-term risk remains elevated. A better entry point likely depends on margin recovery and clearer signs that residential demand is stabilizing.
+Did Lennox International report weak revenue too?
No, revenue was a positive in the quarter, rising about 10% year over year to roughly $1.6 billion. The problem was that profit and margins did not keep pace with sales growth.
+What does Lennox's guidance cut mean for investors?
It means the company now expects less earnings power than previously forecast, which lowers the stock's near-term valuation support. Investors should now anchor expectations to the new EPS range rather than the prior outlook.
